The Science

A Philosophical Perspective on Free Will The Prototype

  • Three scientific works at play

– A history of free-will – A meta-language for thinking – AI’s with multiple personalities

A Practical Perspective on Free Will

“Free will is a fictional construction, but it

has applications in the real world” Steven Pinker Closing the Loop: The Gin and Tonics Test

Jimmy: In Search of Free Will

  • An open platform to involve and engage the wider

community in the science and the search

– Emergent ‘solutions’ from the community

>Interaction with the competition environment

– Developing (programming) Jimmy controllers – Community assessment of the controllers free-will (assessment fed back to the developers as a ranking)

iWorld: An Interactive 3D Virtual World

  • ‘The Hex’ – A futuristic space bar

– Multiple floors – Floors contain a number of rooms – Rooms contain objects and avatars

> Objects: replicator, table

– Smart devices that communicate state information – Future enhancements: music player, video screen, curtains, etc.

> Avatars

– Jimmy (controlled by a programmed AI) – Simon (controlled by a human or AI)

Competition Operating Scenario

  • From the perspective of a contestant

– Download the development toolkit

>Use the validation tool and API to design and implement a Jimmy Controller

– Submit Jimmy controller to the competition System (via a secure submission web page) – Contestants login to the iWorld

>Wander around

– Either act as a Simon, or observe, evaluating controller performances

– Guest reviewers also allowed – Receive periodic controller rankings

The Simon Jimmy Interface

  • The set of

messages passed between Simon and Jimmy and also the intelligent devices in the iWorld

– A rich vocabulary

  • i.e. the replicator

– Can serve a number of drinks – Occasionally serves the wrong drink

Controller Design

  • Goal, design and implement a Jimmy

controller that displays behavior indicative

  • f free will

– Leads to a favorable controller ranking

>Judged against subjective, objective and technical assessments

– Leads us to answer some of the open questions

>Hopefully some interesting solutions will emerge out of this process

Controller Evaluation

  • Three tiered strategy

– Subjective, blind review uses contestants in the iWorld and optional expert guests – Objective, scored against a set of objective ‘free-will’ actions – Technical, evaluation based on responses given to a questionnaire and controller design

  • Overall score a weighted sum of the above

Objective Measurement of Jimmy’s Free-Will A Rule Based Jimmy (Trivial)

  • If rule base of sufficient complexity this type
  • f controller may fit with the ‘compatibilist’

version of free-will

slide-9

7/31/11 9

A Random Jimmy (Quantum)

  • This type of

controller may fit with the ‘libertarianism’ version of free- will

  • Possibly a two

tier approach

– Random / All solutions – Determined choice

Interactive Demonstration

Marc Davies gave a demonstration

  • f the iWorld (Jimmy World) online

virtual reality world built using Open- Wonderland (we also have a version in Real-Extend)
